PC Download isn't showing up on the main site. Perhaps it's because I just registered a new account and redeemed/linked my console version. I'll check back later.
Servers buckling under the excitement of Disney Infinity owners trying to redeem their PC platform version!
Or just down for maintenance.
I figured it out. The 'Download PC Game' button would not show up on any web browser until I set my desktop resolution to 1920x1200 for some reason.
